Subwoofer Reviews

Some home theater enthusiasts see automatic equalization as a sonic savior. They believe it guarantees great sound. But it doesn’t.

Held up against the $3,499 Velodyne DD-12+ and other high-end 12-inch subwoofers that populate the CEDIA Expo, the $399 Cadence CSX-12 Mark II seems incredibly affordable.

Bob Carver has always been a speaker designer who thinks outside the box, and also one who tends to ignore so-called experts when they tell him something can’t be done. As the founder of Phase Linear in the 1970s, Carver in the 1980s, and, more recently, Sunfire, Bob has been proving “experts” wrong for over 40 years.

A great example of his unconventional thinking is the Sunfire True Subwoofer, first launched some 15 years ago. Using a brute force approach, this design bent the rules that traditionally defined how much bass you could get from a given size of driver and enclosure, in the process creating what has gone on to become one of the most imitated subwoofers of all time. Now that same mindset has been applied to creating the Dynamic Series SDS-12 — a lower-cost brother for the True Subwoofer, with an asking price 75% less than the original.

Dr. Poh Ser Hsu designed and sold his first subs around 1991. They were tall, tube-like structures, built from the forms used to pour concrete pillars. The tubes were made of relatively thin fiberboard (roughly 0.125 inches thick), and their cylindrical shape made their walls tremendously strong and resistant to flexure. More important, they were relatively light, which was ideal for Hsu’s direct-from-the-factory sales plan.

One could argue that it’s silly to make a subwoofer look nice. Most subs get shoved into out-of-the-way places where even the most exotic wenge veneer, doused in seven coats of hand-rubbed lacquer and applied to gracefully arcing side panels, won’t really look any better than the cheapest black vinyl wrap glued over a plain rectangular box.

Those who find ugliness a virtue in subwoofers will love SVS’ new $769 PB12-NSD, which is about as plain as subwoofers get.

Romantics see Italy as a place of rich history and sophisticated culture. Not me. As a non-romantic, I can think of Italy only as the birthplace of the Fiat 128 that often left me walking instead of driving, and the location of a honeymoon in which I fought frenzied traffic and struggled to find a decent meal.

From an audio standpoint, the CEDIA Expo used to be little more than a showcase for in-wall speakers and other products built mainly for multiroom systems and custom home theaters. But with the decline in home sales over the last few years, the custom market isn't so hot anymore.
